IMPROVEMENT IN VAPOR-BURNERS.

Specification forming part of Letters Patent No. 92,537, dated July 13,1869.

a vertical section of a modification of the same.

Similar letters of reference represent correspondin g parts.

This invention relates to certain improvements on that class of lamp-burners in which the vaporized hydrocarbon escapes through small apertures from the burner, the jets thus v produced being ignited.

The object of the present invention is to s construct them that the light may be extinguished without producing any smoke.

rlhe vapor-burners now in use cannot be adj usted for larger or sma-ller lights, and can only be extinguished by blowing out the llame.

Much smoke is produced by the latter pro-v cess, and a consequent disagreeable smell.

A, in the drawing, represents my improved burner. rlhis is made of a circular top plate, a, and conical base I), the latter projecting from an upright tube, c.

The plate b has a series of very ne aper-v tures, through which the gas can escape. The lower end ot' thetube c has a flange, d, formed on it, which serves as a handle for turning and raising the burner on the wick-tube B of the lamp.

The wiel; in the tube B raises the liquid,

which is vaporized by the hea-ted plates of the burner, and escapes in jets through the apertures of the same to form a series of llames. When the burner is lowered to a certain degree there is a certain compressionv produced on the gases, which will cause the escape to be more rapid and the ames to be larger. Above and below this point the ilames will become smaller.

By means of the button d the burner can be readily raised or lowered on the wick-tube to produce a stronger or less light.

The top plate of the burner carries an upwardprojecting cap, or rather socket, e, which, when the burner is lowered, will iit over and entirely close and cover the wick-tube. The same cap mayalso be made to project from the under side of the plate a, as in Fig. 2, to lit into the top end of the wick-tube. The same cap may also be made to project from the under side of the plate a, as in Fig. 2, to fit into the top end of the wick-tube, for the saine purpose, to the same eli'ect. When ldie wick-tube is thus closed, by letting down the burner the light will be extinguished, and all escape of gas and smoke most eitectually prevented. A

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The upward or downward projecting cap c formed on the vapor-burner, substantially as described, to close eftectually over or into the wick-tube, as set forth.
